cartrnn'rnns IMPLEMENT.

Be it known that'IjNA'rmN P. CRAMNER,

' a citizen of the United States, residing in Long Branch, Monmouthcounty, New Jersey, have'invented a certain new and useful Improvementin Carpenters Implements;

and I (lo-hereby declare the following to be a full, clear, and exactdescription of the invention, such'as willenable others skilled in theart to which it appertains to make and use-the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

beve squares and the like.

. This invention relatesto carpenters tools and articularly toimplements kindred to Its principal object is to provide a simple, inexensive and compact implement whereby t e work of' cutting jack rafters,cripple rafters and thelike, where the cut presents two angles onadjoining facesof the timber, may be facilitated, the implement being soconstructed that any desired angle may be marked on either of twoadjoining faces of the timber with the assistance thereof.

Figure 1,. in theaccompanying drawing, is

a perspective view of the improved implement in position on a timber tobe marked;

Fig. 2 i-s-a top plan view of the implement Fig. 3 is afront elevationthereof, partly-in section; Fig. 4 an end elevation, looking from theright in Fig. 2 or Fig. 3-; Fig. 5 is a cross-sectional view of thbody-member of.

end thereof and at the angle, the same penetrating only the outer plateI), and being just sufliciently wide so that in the top or the frontelevation of the'member the space d will be uncovered. The two outercorners at this end of member a are preferabl cut away, as'at f. Betweenthe plates 1; are arranged the blades or rules 9 g,one occupying theportion of' the spaced in member a, at one side of its angle and theother occupying the portion of said s ace at the other side of planesintersecting each other. Blade 9 isof such length that it may he slidback into splace d and be substantially entirely s eathed member a; theother blade is preferably made somewhat longer. when blade 9 is fullinclosed in member a, the implement m'a b e used. simply as a bevelatone end but has its other end cut at a suitable acute angle, as at h h;each blade, furthermore, is formed with an opening 7 'i almostco-extens'ive with the length and width thereof and shaped to conform tothe exterior configuration of the blade.

As will be obvious, the slot ve perm-its either blade to be moved to anyangle in the plane of the portion of space (1 which it occupies, andinorder to clam each blade in each having its threaded stem Z Z screwedinto the late I) and penetrating loosely the plate 1;, eing formed witha shoulder m m which abuts against the late I).

Referring to Fig. 1, an in view of the fact that the opening '1, (6,) ofeach blade occupies an a reciable ortion of the length and breadth ofthe' lade and in view of the further fact that each blade has one endThus,

thereof formed as an acute angle, by manipu lating the set-screws theblades may be set at any desired angle relatively to each other and insuch manner as to produce substantially a continuous working edge toguide a pencil or other marking implement in drawing a line across thetwo adjoining faces of the timber A. For instance, in Fig. 1 the bladesare shown each at an angle of a considerable number of degrees, while inFigs. 2 and 3 one blade 9 is arranged at an angle but of a very fewdegrees, and yet in both cases the working edges afford a substantiallycontinuous or unbroken guide for a encil or other marking implement. If,one blade already being set at a desired angle, it should be necessaryto change the position of the other, since the open form of the bladesmakes it possible for each to be reversed (that is, for instance, bybringing its square end where its pointedend appears in the drawing),this may be done in suchmanner as to reserve the continuity of the guideformed by the two working edges of the blades.

Havin thus fully described myinvention, what I c aim as new and desireto secure by Letters Patent is i 1. A carpenters implement consisting,in combination, of a body-member, blades held in intersecting planes insaidbody-member, one of said blades being movable in-its plane to anydesired angle and having an opening extending substantially from end toend thereof, and means for clamping the movable blade in thebody-member, said means penetratin the opening thereof, substantia ly as2.

3. A carpenters implement consisting, in

combination, of a body-member comprising two pairs of arallel spacedwalls, the. walls of each pair heing arranged at an angl to each otherand the relatively outer pair of walls having aslot between them, bladesheld in intersecting planes between {said walls, one blade being movableinto said slot the walls of eac pair being arranged at an angle to eachother and the'relatively outer pair of walls having a slot between themat one end of said member, blades held in intersecting planes betweensaid walls, one blade being movable into said slot and having anopening, and means,'penetrating said openclamping the movable blade insaid member, substantially as described.

5. A carpenter's implement consisting, in combination, of a body-membercomprising aninner angular plate and an outer angular plate disposed inparallelarrangement, said plates having their corresponding edges reenttoward each other and the rebent edge of the one receiving the rebentedge of the other, blades arranged'in the space between said plates oneon one side and the other on the other side of the angle formed in saidmember, each blade bein movable in the ing and disposed adjacent to saidslot, for
